Good news! My fake Polar H7 Bluetooth heart Rate sensor works on my ESP32 using the Arduino IDE. I will show you what I had to do. And much more!

Today I can show you
- How you can build a sensor which sends data via BLE to a client
- A client which can receive these values and display them in Serial Monitor
- The mysterious BLE2902 client characteristic configuration and how it works
- The details of the protocol used by the heart rate measurement characteristics. This will help you to build other sensors based on different standardized services and characteristics
